The Sonic Token, also known as the Sonic Coin, is an object that appears in the Sonic the Hedgehog series. They are gold coins with Sonic's face on them, and are either used to unlock features in or proceed with the levels.
Sonic Tokens first appeared in Sonic R. In this game, there are five tokens to collect on each course during the Grand Prix. Collecting all of these tokens while coming in within the top three positions of the race allows the player to race an unlockable character (except Robotnik and Super Sonic). Once this new character is beaten in this race, the character will be unlocked.
The Sonic Token sets' locations and the character they essentially unlock are as follows:
- Resort Island - Metal Sonic
- Radical City - Tails Doll
- Regal Ruin - EggRobo
- Reactive Factory - Metal Knuckles
In Sonic Adventure and its enhanced port Sonic Adventure DX: Director's Cut, Sonic Tokens had the Sonic Team symbol on them (which still resembled Classic Sonic's face anyway). They are used in Sonic's version of Casinopolis, where he needs to collect four hundred Rings in order to finish the Action Stage. When Sonic makes the deposit using a switch (mechanical pincers grab and violently shake the rings from him) his collected rings will be converted into Sonic Tokens (1 Ring = 1 token) and pile up in the vault.
Knuckles can see Sonic's tokens in his version of Casinopolis as well.
During missions, some missions will require you to find Sonic Tokens which are described on the cards as medallions.
SegaWorld also used actual Sonic tokens. These were used to play the prize/ticket games in SegaWorld. Sonic tokens in London had Sonic's classic pose on one side, while the other side had the Sega logo.
The Sonic tokens in Sydney were more traditional to the games, as one side had Sonic's head while the other had SegaWorld Sydney's logo on it. Various SegaWorlds also used Sonic Tokens to play the games.
- In console/PC version of Sonic Generations, the Challenge Act Knuckles: Buried Treasure has Medals resembling Sonic Tokens, but with Knuckles's face imprinted on them.
